AI Ethics Explained: How to Use Artificial Intelligence Responsibly
Have you ever used ChatGPT to help explain a difficult topic? Maybe you've asked Gemini to summarize a lengthy article, generate ideas for a school project, write an email, or even use Claude for brainstorming concepts. If you're a student, you've probably wondered: "Is it okay to use AI [...]
Fine-tuning an LLM for natural Tagalog speech
If you're an ML engineer or a technical lead planning to pre-train a large language model (LLM) for Tagalog or Taglish, how do you start? In this article, we walk through the process of defining a target voice, building a data pipeline, running a QLoRA training experiment, and evaluating [...]
Building Diffender: A Serverless AI Security Reviewer for GitHub Pull Requests with Amazon Bedrock
A pull request can pass its tests, satisfy its acceptance criteria, and still expose a production credential in one line of code. Diffender is an Amazon Bedrock pull request reviewer built to identify that kind of risk before the change reaches the main branch. However, human review remains essential, [...]

CI/CD Crash Course: From Junior to Senior Developer
Continuous Integration and Continuous Delivery/Deployment (CI/CD) is the backbone of modern software teams. It's not just a buzzword for your resume — it's the automated pipeline that takes code from "it works on my machine" to "it works in production, reliably, every time." Understanding CI/CD deeply, not just using [...]
Everything You Need to Know About Harness Engineering
AI agents can now write code, browse the web, and run for hours without a human watching. Ask one to build a feature, and it might open ten files and call five tools. It can make a hundred small decisions before it ever shows you a result. That is [...]
Should the Philippines Make Its Own Local Large Language Model?
As countries all around the world are beginning to invest in their own large language models, the same question keeps coming up in Philippine tech circles: should the country build one, too? If we do, would it be cost-effective? And if it is, would it be beneficial? As [...]

AI Influencers: How Generative AI Is Quietly Taking Over Affiliate Marketing

I was casually scrolling through TikTok and Shopee the other night when something caught my eye. A woman appeared on screen holding a product. She smiled, explained why it was amazing, and made it look effortless. Perfect lighting, flawless background, delivery smoother than butter. I shrugged. Normal influencer video, right? Then another video popped up. Different product. Different “influencer.” But wait… the vibe felt eerily familiar. The gestures, the expressions, the way she spoke—it [...]

AWS Data and AI Journey: Modernizing Your Data Foundation

Stage 1 of the AWS Data and AI Journey: Modernizing Your Data Foundation Artificial intelligence systems are only as powerful as the data infrastructure supporting them. Many organizations want to adopt advanced AI capabilities, but they quickly discover that their data architecture is not ready. Data may be fragmented across systems, stored in legacy databases, or difficult to scale. Before machine learning, generative AI, or autonomous agents can deliver meaningful outcomes, organizations must first [...]

The Economics of AI Infrastructure: Understanding AWS AI Factories

Artificial intelligence has shifted from being a software innovation challenge to becoming an infrastructure challenge. Organizations no longer struggle primarily with model design. Instead, organizations are increasingly challenged by compute density, energy consumption, networking scale, and operational complexity when deploying modern AI systems. As large-scale generative AI systems become central to business strategy, infrastructure decisions now carry long-term economic consequences. This is the context in which AWS AI Factories emerged. First announced at AWS [...]

Deploying an AWS Application Load Balancer (ALB) Using Terraform

If you’ve tried building an ALB manually in the AWS Console, you already know the drill create a VPC, configure subnets, set up security groups, launch Amazon EC2 instances, create a target group, add listeners, and then double check everything because one small misconfiguration can break the whole setup. It works, but it’s time consuming and not something you want to repeat every time you need a fresh environment. This is exactly where Terraform [...]

How to Break Into Tech (With Security in Mind)

Let’s talk honestly for a second. If you want to break into tech securely, you need to think differently from the start. A lot of people say they want to “break into tech,” but very few think about structure, architecture, and security from day one. What they usually mean is: Get a remote job Learn to code Work in AI Do cybersecurity Escape something Nothing wrong with that. But here’s the uncomfortable truth: Most [...]

Stop Running OpenClaw on Your Laptop: How I Built a Secure Personal AI Assistant Using Amazon Bedrock

I'll admit. The first time I heard about OpenClaw and its features, I was obsessed. The idea of having an AI that could actually do stuff rather than just giving responses to prompts felt like living in the future. As a university student, it’s a given that I have a lot of responsibilities to keep track of. Be it responding to school emails, checking telegrams for assigned work, or simply knowing when the next [...]

Improving Application Security with AWS Security Agent

Modern software teams are very fast today. Code is pushed daily. Pipelines deploy automatically. Features reach users quickly. This is the success of DevOps. But security often does not move at the same speed. In many organizations, security reviews are still scheduled monthly or quarterly. Penetration tests require coordination. Findings come late. When issues are discovered, teams must pause releases and fix problems under pressure. This gap between fast development and slow security creates [...]

Real-time Personally Identifiable Information (PII) Redaction Pipeline with S3 + Lambda + Comprehend

In my previous article, I demonstrated how to use the Amazon Comprehend console to manually detect and redact Personally Identifiable Information (PII) from text files. While this hands-on method is excellent for learning the fundamentals of PII detection, it’s not practical in real-world, high-volume environments where speed and accuracy are essential. In such scenarios, organizations need more than just a simple, one-time approach—they require a robust, fully automated pipeline that sanitizes sensitive data as [...]
